Abstract (en)
[origin: WO8700476A1] A deceleration control circuit (18) is provided for a profile controller which controls motors (12X to 12Z) relying upon displacement signals ($g(e)X to $g(e)Z) from a tracer head (1) that traces the surface of a model, in order to control a relative feed between the tracer head and the model, thus making it possible to control the deceleration depending upon the shape of a point where the model changes abruptly. The deceleration control circuit compares a plurality of threshold values with variations of displacement signals ($g(e)X to $g(e)Z) per unit time, and controls a relative feed speed between the tracer head and the model depending upon to which area determined by said plurality of threshold values said variations belong.
